I own both an HP-C and an Eclipse BCS. In my opinion the Eclipse is the best all around choice especially if you are using acrylics. The Eclipse is a little easier to clean which is a plus. Another big advantage to the Eclipse is the width of the spray pattern which allows for faster coverage. The HP-C is really good when you are doing fine lines for camo patterns on 1/72 scale aircraft. Hope this helps.
